In John Barth's novel "Giles Goat-Boy," the character reflects on the nature of education and its unintended consequences. Despite the teacher's good intentions, the students often misinterpret the lessons and use them negatively, leading to unhappiness among their peers. This highlights a disconnect between the intended message of guidance and the reality of how knowledge can be wielded to create conflict.

The quote encapsulates a broader critique of educational systems, suggesting that they can produce individuals who are intolerant of differing opinions. Instead of fostering a constructive dialogue, the students become judgmental and punitive towards those that express dissent. This serves as a commentary on the challenges within academic environments and the importance of nurturing open-mindedness rather than fostering an atmosphere of exclusion and misery.
